when your in a boat, riding in a nether hub (ice road from portal to portal, over the nether)

when you get out of the boat, you fall trough the ice block its on, and you fall into the lavalake in the nether the road is over,      this happened before with an minecart over the nether,

getting out of the boat or cart, makes u fall through the block its on.

fix it, becouse losing all of your stuff in lava becouse of an glitch isnt funny
